CEDAR team's work published in Communications Biology

Jose Ajay

CEDAR researchers Jose Luis Montoya Mira and Ajay Sapre, alongside teammates Kyle Gustafson, Gene Tu, Jared Fischer, Roger Chiu and Sadik Esener published "Label-free enrichment of rare unconventional circulating neoplastic cells using a microfluidic dielectrophoretic sorting device" in Communications Biology on September 24. The team reported on the development of a label-free dielectrophoretic microfluidic platform facilitating enrichment of CHCs in a high-throughput and rapid fashion by depleting healthy peripheral blood mononuclear cells (PBMCs). This represents a promising approach to non-invasively analyzing tumor cells from patients.

Defense Department Idea Award for CEDAR's Thuy Ngo

Thuy Ngo Kuni

Thuy Ngo, Ph.D., has received a Peer Reviewed Cancer Research Program Idea Award from the Department of Defense for a project to identify blood biomarkers for early diagnosis and treatment monitoring of liver cirrhosis and cancer. Ngo is an Assistant Professor of Molecular and Medical Genetics in the OHSU School of Medicine and a member of CEDAR, the Knight Cancer Institute's Cancer Early Detection Advanced Research Center. Liver cancer, or hepatocellular carcinoma, is the fourth leading cause of cancer-related deaths worldwide. Current clinical blood tests have low sensitivity to detect liver cancer at early stages and are not effective for the reliable diagnosis of cirrhosis, which puts people at high risk of liver cancer. Patients with liver cancer are often diagnosed with inoperable disease. The Department of Defense award — $769,996 total — is supporting Ngo's proposal to identify cell-free RNA biomarkers (including messenger RNA, circular RNA, transposable elements and microbial transcripts) that can detect cirrhosis and monitor its progression to liver cancer. 

Thuy Ngo awarded Komen grant

The Susan G. Komen Breast Cancer Foundation announced 30 new grants to leading researchers across the U.S. and Canada — including CEDAR member and Assistant Professor of Molecular and Medical Genetics Thuy Ngo, Ph.D. Ngo was awarded a Career Catalyst Research Grant to study the use of cell-free RNA found in blood as a way to monitor if a treatment is successful for patients with metastatic breast cancer. This method provides the opportunity to gain a deeper understanding of the behavior and characteristics of the metastatic tumor and to monitor changes in metastatic lesions and responses to treatment. A full list of this year's research grants can be found at Komen.org.

CEDAR/SMMART collaboration receives funding from the Kuni Foundation

The Kuni Foundation has awarded almost $1.5 million to a collaborative project between CEDAR and SMMART, a first-of-its-kind platform designed to rapidly identify combinations of drugs that can stop tumors before they adapt and become drug-resistant. Currently, patients must have two biopsies at a major cancer center to enroll in the program. This is a barrier for people who lack the means to access a major cancer center, including rural, BIPOC, and underserved communities. The project, "Blood Biopsies as a Cost-Effective Approach to Democratize Personalized Therapy for OA & WA Patients" is developing approaches that will decrease the need for surgical biopsies by analyzing blood samples for material that escapes from tumors and goes into the blood stream. This blood can be drawn at any clinic and shipped to OHSU. The features CEDAR's Thuy Ngo as a Co-Investigator; Gordon Mills, director of precision oncology at the OHSU Knight Cancer Institute, is the Principal Investigator.

Joshua Saldivar

CEDAR's Joshua Saldivar, Ph.D. was recently named one of the 100 most inspiring Hispanic/Latinx scientists in America by Cell Press's Cell Mentor. In honor of National Hispanic Heritage Month, Cell Mentor showcased 100 of the United States' most impressive Hispanic/Latinx scientists. The list—selected based on scholarly achievements, mentoring excellence, and commitment to diversity, equity, and inclusion—highlights scientists across academia, government, and industry. Dr. Saldivar is an Assistant Professor of the Division of Oncological Sciences and a CEDAR scientist. His work focuses on how cells coordinate nuclear processes, such as DNA replication and transcription, through various signals, epigenetic marks, and chromatin regulators that intersect within phase-separated condensates. He uses cutting-edge microscopy approaches and powerful sequencing technologies to uncover the elegant and dynamic biology of chromatin. His long-term goals are to understand how these nuclear processes become destabilized in premalignant cells and drive epigenetic reprogramming and malignant transformation, as this will help us determine which early cancers are likely to become lethal. He joined CEDAR in Fall 2018.

OHSU joined forces with MIT Hacking Medicine and academic and industry partners to throw the inaugural OHSU Invent-a-thon, a virtual healthcare hackathon, from Oct. 23 to Oct. 25. The virtual event brought together problem solvers and thought leaders from across disciplines and geographic boundaries, offering teams the opportunity to pitch original solutions to tackle pressing health care challenges. Two teams led by CEDAR staff took home prizes from the Invent-a-thon. CEDAR Graduate Student Zeynep Sayar's team won 1st place in the Early Disease track and won the in-kind prize for "Direct Digital Pathology," which proposes outsourcing the digitization of pathology slides to increase access to and frequency of digitilazation to improve health outcomes. CEDAR Associate Specialist Samuel Tassi Yunga's team won $2000 for their "CommuNutri" idea. This idea proposes diagnosis-focused meal plans to patients with food meal delivery options, directions to pick up fresh ingredients from local farms, and emphasizes culture-appropriate ingredients. It includes a social media ecosystem that connects patients with online nutritionist support. The platfrom can also be scaled up later to include meal plans for the long-term paraclinical management of other diseases.

Hisham Mohammed speaks with the Knight Cancer Institute's Cancer Translated blog

Hisham Mohammed

The Knight Cancer Institute's Cancer Translated blog recently spoke with CEDAR's Hisham Mohammed, Ph.D. Mohammed, an assistant professor of molecular and medical genetics in the OHSU School of Medicine and scientist in CEDAR, helped create a way to peer into individual cells and take multiple measures of gene activity and gene regulation at the same time. He's leading the first efforts to apply that single-cell multi-omic research method to cancer. Cancer Translated spoke with him about the method's prospects for resolving questions into how fundamental biological processes go wrong and begin to regulate and drive cancer—which is key to detecting and treating early cancer.

Aaron Grossberg receives NCI career development award

Aaron Grossberg, M.D., Ph.D., OHSU Knight Cancer Institute

Aaron Grossberg, M.D., Ph.D., has received a Mentored Clinical Scientist Research Career Development Award from the National Cancer Institute for his research on pancreatic cancer. Grossberg is an assistant professor of radiation medicine in the OHSU School of Medicine. He has a joint appointment with CEDAR and the Brenden-Colson Center for Pancreatic Care. Grossberg's lab studies the interaction between cancer and metabolism in an effort to identify ways to diagnose cancers sooner and improve the quality of life of cancer patients. NCI's K08 awards provide support and protected time to non-tenured clinician-scientists at the early career stage for an intensive, mentored research career development experience in basic, translational, or patient-oriented cancer-focused-research. The award will support further research on the wasting syndrome cachexia in pancreatic cancer. The mechanisms underlying cachexia are poorly understood, and there remain no effective treatments. Grossberg's team has found that pancreatic ductal adenocarcinoma alters the regulation of metabolic genes in the liver, the organ that controls whole-body physiology in response to nutrient availability. The researchers are working to understand this deregulation of liver metabolism, its role in cancer cachexia, and the circulating signals that mediate these changes.

Using radiation to boost circulating DNA for ‘liquid biopsies’ of cancer

•	Using radiation to boost circulating DNA for ‘liquid biopsies’ of cancer

Testing for tumor DNA in blood is easier and safer than taking a biopsy of tumor tissue. The problem is, early-stage tumors may not shed enough DNA to find in a blood draw. Researchers at OHSU are working on a way to use radiation to increase the amount of tumor DNA in blood. They’ve shown that patients with suspected lung tumors show a sharp increase in circulating tumor DNA after treatment with stereotactic body radiation therapy, or SBRT.
